Fig. l2 is a plan Vviewo lthe same. Fig. 3v is a transverse sectional'view on the line 1,1 of Fig. l. Figli is a side view of'avrnodiiied forni' of apparatus. Fig. 5, isa plan view of the modification shown in Fig. Ll; Fig. 6 is a transverse sectional view ofthe apparatus shown in Fig. 4 on the line of Fig. 5; and Fig. 7 is an enlarged sectional view 0f. the conveyer-belt and its frame, showing'thearrangement of idlepulleys for the belt.

` Referring to thedrawings', the conveyerframe A is movable relatively to the support 'B :and in .this instance carries a continuous traveling conveyer-belt C, although I vdo not limit myself to a belt conveyer, as any otherv form of conveyer may be' utilized.. The belt may be of any 'suitable character, but is shown inA this instance as a conveyor-belt passing over a series of upper and lower idlerpulleys D land E and the head-pulley F and tail-pulley G, it being Iunderstood that the l SpecicationofLetters Patent. applicati@ ned Mamma, 1903.- sriai Nt.

head-'pulley is that 'pulleyupon theframe at the endof which the material is carried by the'movement of the belt, while the tail-pul- -ley is at the end o f the frame from which the material is being carried.` ,'I'heidler-pulleys D, as shown, are adapted to impart a trough Sllap belt. p

The 'conveyer-.frame A vis lsuitably pivoted to the support B or, as shown' in Fig. 4, to the e to tlie carrying-surface of the conveyer- "support B", and in this. instance the belt is operating 'the oo riveyer-belt, as anyother suitable connections-may beprovided, either mechanical or electrical, and in each instanceA shown in the drawings,l and according to' my invention the driving mechanism referred to iS. .constructed to afford provision for moving the conveyer-frame A or A vrelatively to the support B or-B Without changing the opermeshing with a driving-pinion I .onv

ativeness .ofthe driving mechanism. In

other words, accordingto the -construction shown in the drawings the angle ofthe conveyer-frame relativelyA tov the support to which it is pivoted may be changed Without disturbing the 'driving mechanism or changing its operativeness. In order to accom- 'plish these ends, the conveyer-framemay either be pivoted aboutl the same center as the driving-shaft@ as show-n in Figs. l and 2, or it may be pivoted for movement about the same canteras the shaft L of the tail-pulley G, as shown in Figs. l4.- and 5. In either instance it will be seen that the gear-II will roll` upon the pinionI as the frame A or Ais moved about its pivot', and'theoperativeness I0f the. .driving mechanism will not be" changed or disturbed.. i

In Figs`v4 andy-5 the conveyer-fraine A is coincidentwith;k the axis of the pulley G, one suitable form of my invention being-illustrated. In the drawings the fixed support B is provided with the framei/Q.2 and the frame A is provided with' y beaiigs for the studs R, connected to the 'irme-ognuna ist@mediakrant-bearings for t ejpulleyhaft L, the shaft L and studs Rheingnpon thesarnev airis;` Accords ingto.,thisonstruction there will `be no ing in the bearin of the continuouslyv-rotat'' 'ing shaft Land t, e .thrust come'entirely In `the operation upon thefstuds R. v

,A According to my construction I arrange an idle orsnub4 pulley 52 upon the upper side of the belt C andfadjacent the tail-pulley G.

A'According to the construction of apparatus described the lower vside'of the belt is ini teni' sion while `thel upperv4 side-of the belt is the loose side, and by .arranging `the snub-pulley 52 inthe position described and shown there is no harmful bending over the snub-pulley and fno consequent strain on the snubshaft *and demarre to the belt. The slack of t l' conveyorbelt isp'ushed under the snub-pulley 52', which isv ofprnaterial advantage in the operation of the conveyor.

' Obviously some'features of my invention may be used without others, and my invene tion maybe embodied in'widelyfva'rying'` forms.I

Therefore, ywithout limiting myself to thel construction shown and ,described nor onu#- merating equivalents, I claim, and desire`I to obtain by Letters Patent, the following:

1. In a belt conveyer, the combination' with a suitable support and a frame for the conveyerpivoted thereon, of end, pulieys overvv f whieli the belt runs, idler-pulleys arranged the purposes set forth.
